APPARATUS FOR AUTOMATICALLY CONTROLLING THE OPERATION OF PRESSURE-VALVES.

SPECIFICATION forming part of Letters Patent No;.392,218, dated November 6, 1888.

Application filed March 19,1888.

ToaZZ whom it may concern.-

Be it known that I, GEORGE H. MO0RE,of Norwich, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Apparatus for Automatically Controlling the Operation of Pressure-Actuated Valves/oi which the following companying drawings, forming part thereof. In an application for Letters Patent filed by serially numbered-241,577, I have shown, described, and claimed an apparatus for regulating the operation of the several valves governing the inlet and outlet openings ofa filter in such manner as to automatically effect the becomes clogged by the impurities'eliminatedj from the water during the'process oT-filtra tion.

The object of my present invention is to improve the construction of the regulating apparatus shown in my said prior application, to

dered positive and its effectiveness correspondingly increased.

The invention therefore consists in the apscribed, and particularly pointed out'in the claims. 4 t

. Referring to the drawings, in which like letters designate like parts in the several figures,Figure.1 is a perspective view of the apparatus. Fig. 2 is a front view-ofthe apparatus, three pressureactuated primary Figs. 3, 4, and 5 are vertical sectional views of the three sec ondary valves forming part of the apparatus.

As my present invention relates wholly to the apparatus forregulating the operation of pressure-actuated valves, I have deemed it unnecessary to show a filter in the drawings, but have shown in Fig. 2 threevalves, (designated by the letters A A A*, respectively,)

der pressure, and have shown the apparatus connected by pipes with said valves, as hereinafter described, for the purpose of illustrating theoperati'on of the apparatus in connection .with' pressure -'actuated valves gener ally.

Serial No. 207.005. (No model.)

As shown, the valves A A A", whichI will call primary valves, are composed of a shell having upon opposite sides thereof cylinders pansible cylinder, a mounted at one end upon one of said pistons, and at its opposite end upon a disk, a secured to stem at between the pistons, whereby by admitting fluid or liquid under pressure to the outer ends of cylinders a alternately said pistons and expansible cylinder arev moved in such manner as to cause the latter to open and closethe water-way through the shell. As this'form'of valve forms thesubject of a separate application for Letters Patent filed .by me on the 20th day of May, A. D; 1887, and -serially numbered 238,855, it need not be more particulari described herein; and it will be understooiv that said valve is shown as one example merely'of pressure actuated valves, and that so ,far as my present invention is concerned an 'form of valve adapted to be opened and closed by fluid or liquid under pressure could-be substituted for the one shown. v

The regulating apparatus, which I will now proceed to describe, is designed to be located between said primary valves and the primary source of' fluid or liqui'd nnder pressure, and its oilice is to regulate the'r'passage of said fluid or liquid to'said valvesin such manner as to cause the latter to operate in a predetermined sequence. Y

The letter B designatesa bracket, which supports a series of closed tubes, designated by the numbers 1 to 6, inclusive,- and arranged in pairs, as shown. These tubes, which. I will call distributingreservoirs of power, dis tribute the fluid ori'liquid under pressure to the primary valves by means of suitable pipes, and the admission of said fluid or liquid to and its exhaustion from said reservoirs is gov erned by a series of secondary valves, each secondary valve being connected with and governing two reservoirs, as follows; valve Gwi'th reservoirs 1 2,val veD'with reservoirs 3 4, and valve E with reservoirs 5 6.

Referring to Fig. 3, the secondary/valve G'is composed of ashell, 0, having a central cham- I ber, into which open at the rear side of the duct will be closed.

valve three ports, 0 c 0, and communicating with which'chamber, at the front side of the valve, by means of ducts c c, is a. port, 0". I prefer-to'insert bushings 0 within the valvechamber adjacent to ports 0 0 said bushings being provided with a series ofperforations cated in theplane of said ports, but out of alignment therewith, and to form an annular recess within the inner-wall of the valve in the plane of each of said bushings, as shown, whereby an indirect communication between saidnports c c and the valve-ehamber'is secured to prevent the fluid oriiquid under pressure from exerting a binding action against the valve-plug during the exhaust movement, as hereinafter described.

The valve-plug C has its. ends fitted to the bore of said bushings 0, while its central portion is rcducedin size, as shown, and said plug is of such length that when in its highest position, as shown in Fig. 3,-portsc 0 will be in open communication with each other. Porto will be in open communication with duct 0'' and port c",while duct 0 will be closed; and when in itslowest position ports 0' 0 will be in open communication with each other, port 0 in open communication with duct 0 and port c",while Reservoir l is connected with said valve 0 by means of a short pipe leading from .port a, and reservoir 2 by means of a similar pipeleading from port 0 A pipe, F, leading from the primary source of spectivcly, and also to pipes F G.

mary valves-A A A each having their oppofluid or liquid under pressureas,for example, from-the street-mai n-comm unicates with said valve by means of a short branch pipe leading from port 0, and a similar branch-pipe leads from port c" to a waste-pipe, G, as shown in Fig. 1.

. The construction of valve 0, as thus described, is common to each of the three valves 0 D E, said latter valves being similarly connected to their reservoirs.3 4 and 5 6, re- The prisite cylinders connected to one of said pairs of reservoirs, it follows from the construction of the secondary valves, as just described,.that when the plug of either of the latter valves is in its highest position the fluid or liquid under pressure will pass from-pipe 1 through said valve to the upper reservoir connected therewith, from whence it will pass to one of the cylinders of the primary valve connected with that pair of reservoirs, moving the gate of such primary valve to open or close the latter, as the case may be, while the fluid or liquid-will exhaust from the opposite cylinder of said primary valve through the lower reservoir and said secoridary valve to pipe G. It follows, furthermore, that when the plug of either of said secondaryvalves is in its lowest position this movement of the motive fluid or liquid will be reversed-that is to say, it will then pass from pipe F to the lower reservoirlconnected with said valve, and from thence to the opposite cylinder of the primary valve, moving the gate thereof .in the reverse direction,

while the exhaust m-ovementwill occur through the upper reservoir and said secondary valve to pipe G. Provision is thus made for controlling the movement of the primary valves by the movement of the secondary valves, and it only remains for me to describe the means by which the secondary valves are themselves operated, and the means by which their movementsare made to depend upon each other in such manner asto cause-themto operate in a predetermined sequence. I

The letter Hdesignates a hollow cylindrical receptacle secured to the stem of plug 0 of valve Oabove-t'he valve-shell, and Idesignates a chain' secured at oneend to said cylinder H, said chain passing over a pulley, K, and having secured to its opposite end a weight, K, which normally retainssaid cylinder and valveplug 0 in their highestposition. A pipe,H', communicates with the interior of cylinder H,

at thetop thereof, and a pipe, H, leading from said cylinder, atthe bottom thereof, projects into the vertical extension L of ya waste-pipe, L, the mouth of-said pipeH being normally closed by a ball-valve, as shown by broken lines in Fig. 3. A'rod depending from said ball-valve, as'shownfopeim said valve when the cylinder ,H descends,.the end of said rod being thereby brought into contact with the bottom of pipe L.

As thus far described, the construction of the regulating apparatusis identical with that shown and described in my said application, Serial No. 241,577, and in that case the pipe H leads from the upper compartment'of a'filter,

whereby the'excess of water in the filtryeaused v can be governed ,by any-suitable manuallyoperated valve located-in said pipe.

As previously stated, the valve governing the outlet-pipe H is opened by the descent of the cylinder, permitting the water to escape from the latter into waste-pipe L, and the time required to empty the cylinder will be governed by the size of saidoutlet-pipe H", whereby the time during which the cylinder will remain in its lowest position canbe accurately predetermined.

In the'ap'pa'ratus dcscribe( in mysaid' application,Serial No. 241,57 7 ,t e secondvalvc,

corresponding to valvei), is also provided with acylinder and weight'for operatingit,' while the third valve, corresponding to valve E, is provided witha weightto normallyretain its plug in its lowestgposition, said plug being' moved upwardly by the fluid [or liquid under pressure distributed to said valve from the reservoirs governed by'the first and second valves.

In my presentjin'vfention the valve D, which is shown in section in Fig. 4, is provided with a cylinder, D, at the bottom of its shell, containing a piston, d, the stem of which extends through the bottom of the valve-shell, where it is adapted to bear against the bottom of plug D'. Said valve is also provided with a cylinder, D at the top of its shell, and the stemof plug D -is extended through the topof the shell into said cylinder and connected at its 10. upperend with. pistgn d. within-thela-tter2*A weight, D, 'is'secure'd to the upper end of a rod, diiwhich rod passes through the upper head of cylinder D and rests at its lower end upon piston d, the rod bein-g preferably made 1 +-shaped in cross section to increaseits rigidity. Valve E, (shown in section .in Fig. 5)

is also provided withcylinders E E at the top.

and bottom of its shell, the former being elongated, as shown in Fig. 1. Within cylinder E" is located a piston, e, the stem of which extends 'into the valve-chamber, where it is'adapted to bear against the bottom of plugE The stem of said plug E passes througli'the topof the valve-shell into cylinder E, ,shown, and within-said eylinderis located-'aloose piston, e,-p'referably consisting of two heads united by a stem, as shown, said heads being closely Y fitted to the bore of the cylinder, so that said piston will remain stationary,-except when pressure is exerted against one or the other of li-gitsheads.

' A pipe, M, connects reservoir Z WiQll QVllIL;

I as shown, and branch pipes at m connect said pipe 'M with cylinders D E, respectively,

entering said cylinders through the bottom thereof. A pipe, N, connects reservoir 1 with cylinder E, entering the latter at the top thereof, and in said pipe is located a checkvalve, 12, which is of the usual form, and which obstructs the passage of fluid or liquid through pipe)? to the'cylinder, but permitsthe same to pass freely through said pipe from the cylinder. 'A branch pipe, N, containing valve a, c nnects thatportionof pipe N upon one side. i" valve n with the portion thereof iipon the'opposite-side of said valve, as shown in Fig. 1. Su'ph construction enables me to regulate the admission of fluid orliquid tothe upper end of ,cylinder E by means of valve in, .while a frec\ exhaust movement thereof from said cylinder at its upper end is permittedbycheck-valve n. An additionaLpipe, 'O, con-' nects reservoir 6 with ,cylinder D? the latter nearthe bottom thereof.

cylinders onnected with the reservoirs by pipes, as follows: valve A by'pipe a with res ervoir l and" by pipe at withreserveir 2,-valve A by pipe'a'kwith reservoir '3 and by pipe at .with reservoir 4,'and valve A by pipe a with reservoir ,5 and by pipe a with reservoir 6. v The operation of the apparatus thus constructed is as ijollows; Presuming pipe H to -lead from some convenient source of water- T suppl'y,'pipe E -to leadi'rom a suitable source enteringz of fluid or liquid under pressure, the plug of valve 0 to be in its highest position and thatof valve E to be in itslowest position,the plug of valve D will be held in its highest position by the fluid or liquid under pressure distributed from reservoir 6 through pipe 0 to cylinder D"; In this positionfof said secondary valves primary valves'A A M vill b.e,elosed,;

as will be oluvious from, the"iahdvegiescribedarrangement of the distributingpipes leading to said valves,and by reference to Fig. 2 of the drawings. The parts will remain in such position until water isadmitted to cylinder H through pipe H, and by filling said'cylinder 8o Simultaneously with such movement the fluid or liquid under pressure passes from said reservoir '2 through pipe M to cylinders D E E moving piston d in the former to its highest position, where its stem abuts against the lower end of plug D and moving pistons e e 5 to their highest position, the former carrying with it plug Eof valve E. By this movement V of; valyeEthefluido iliquid-under.pressure der E, entering the latter near its lower end,

is permitted to pass from pipe F to reservoir '5, and from thence through pipe a 'toprimary we 1 valve A", opening the latter,the exhaust move ment therefrom occurringthroughpipe a? and reservoir 6 to pipe G. A Similar exhaust movement occurs from cylinder 1) of valveD through pipe 0; but theplugDi of said valve is still retainediii' its highest position by pis ton (Z, which has been moved to its highest position, as just described; p

The time during which the parts will remain in the last-describedpositionthat is to say, 1 In with primary-valvesA and A open, valve A still being closed -is governed by the size of outlet-pipe H of 'cyliuder'H, as previously stated, which will-be regulated according to 1 the function performed by the several primary 1 z 5 valves in the particular organization withwhich the apparatus is used. I

As soon as all the water withincylinder H has escaped therefrom, weight K returns it to its highest position, thereby again admitting r20 thcfiuidbr-liquid from pipe]? to reservoir 1', Primary valves AA A have their opposite and closing primary yalve A, the exhaust movement occurring through. pipjcqai andrcservoir 2. An exhaustmovement-also occurs through'pipe.MfromlcylinderSDeE E, therei25 by permitting weight D to move plug D -of valveyD to its lowest position.. Such move-- fluid or liquid to pass from reservoir lthrough pipe N; but as it cannot pass check-valven said fluid or liquid is diverted through pipe 7 N, and its passage through the latter pipe to c3 ii nder E is governed by valve 11,, asihereinbefore d cribed. Said valve n will beset in such manner :hatihc time required'i'or the fiuid'or liquid permitted to pass therethrough to move piston e from the top to the bottom of cylinder B will correspond to the time desired to elapse between the last-described movement of the primary valves and the next movement thereof. As said piston e approaches the bottom of cylinder E, it is brought into contact with the upper end of the stem of plug E and by its continued movement returns said plug to its lowest position, thereby causing the iluid or liquid to be distributed from reservoir 6 throughpipe a to primary valve A closing the latter. At the same time the passage of said tluid or liquid from reservoir 6 through pipe 0 to cylinder D moves piston d and plug D of valve D to theirhighestposition,-whereby by distribution of the flnid or liquid from reservoir 3 through pipe a primary valve A is closed, and the parts are restored to their normal positions, ready torepeat the above-described operation whenever water is again admitted to cylinder H.

it will be observed from the foregoing description that from the time when water is ad mitted to cylinder H-the apparatus assumes entire control of the primary valves and automatically eansesthmto' operate in a regular sequence, the intervals between theseveral movements thereof being accurately predcten. mined. it will be observed, furthermore, that the movements of the secondary valves are positive in bothdirections, and that the movements of two of said valves are dependent upon the movement of the third valve.

It is obvious that the number of primary valves to be operated from either pair of res.- ervoirs can be increased or diminished at will, and that the relative movements of said valves will be governed by the particular reservoirs to which their opposite cylinders are connected. I therefore do not wish to limit myself to the' exact number of primary and secondary valves and reservoirs, nor to the-exact rrut-ive arrangement of said parts and their cc iiiQblllg-PlPGS, hereinshown and described, as .iiodifications therein can be made without departing from the spirit of my invention.

Having thus fully described myinvention, what I claim, and desire to secure by'Letters Patent, is-
